Anyone tried 351 Mercruiser heads?? March 16, 2012, 04:59:10 PM I was working on my 93 Tbird in my shop today (My redneck friend ran it over coming home from the bar one night in his big truck, he thought it was funny as heck, but I didn't think so) and my landlord seen the pile of 302s I am working on. He said he had a pile of 351 mercruiser heads lying around and he figured they would be better than the stock heads. Anyone tried a marine head head before? Quote Selected

Anyone tried 351 Mercruiser heads?? Reply #2 – March 16, 2012, 11:45:02 PM From what I seen earlier today they look similar to 289 heads. Small cc chamber and no smog humps. They look like they will bolt right on, but I'd have to check the head bolt size. Quote Selected
